Abstract: An illumination device for fluorescence image guided surgery and a surgical instrument. The illumination device includes a glass rod, a mixing rod and a plurality of optical fibers surrounding a circumferential surface of the glass rod. A first mixing rod end face of the mixing rod abuts a second rod end face of the glass rod and end faces of the optical fibers, so that white light and excitation light are guided and homogenized in the mixing rod.

Abstract: An illumination device including an illumination source having a light source; a sensor; and a processor; and a light guiding cable having main and secondary fiber bundles. The light guiding cable comprises a first end coupled to the illumination source and an opposite second end configured for coupling with a surgical instrument such that the light source provides the surgical instrument with light from the light source. The first end is coupled to the illumination source such that light from the light source is coupled into the main fiber bundle and light guided in the secondary fiber bundle is directed to the sensor. The processor receives a signal from the sensor indicative of an illumination level at the sensor and generates a control signal if the illumination level of the sensor is above a predetermined threshold value.
